SHUTTLE.

Application filed April 14,

This invention relates to shuttles and it has for its objectto rovide a shuttle with, a tension devicewhere y the threading can be accomplished by enti of the thread or filling transversely of itsel and as an, incident to automatic replenishing of the fillingsupply and to produce a shuttle of this kind which will operate at all times with reliability and can be made at little expense and whose parts replacement or repairs. 3 7

The shuttle bod 1 has theusual cavity 2 for the filling pac age 3,:the same being extended at 4 forwardandbeing open at the channel 5'leading forward from the cavity 2+4and adapted to permit the filling to enter downwardly intorthe cavity. At the near side of'the body 1 in Fig. 1 is the filling outlet 6 with which communicatesgeaching down wardlyfrom the top of the 'shuttle,-a1 slit .7,

I whereby when the filling is formed in a bight',

as will hereinafter appear, it: obtains access tothe outlet. I a i The improved tension device comprises two principal parts, a housing and a, tension Y lever-thelatter being elastically controlled.

The construction and arrangement of these 7 parts are the factorsresulting in producing a shuttle of the present kind which is at once efficient in operation, simple and inexpensive in construction and capable of being readily kept in good working order. The housing, 8, is struck up from a sheet'metal blank so-as to produce a bottom wall 8, two side walls 8", an open frontend, a rearwall 8 and atop wall 8 The *top and rear walls are. constructed to permit the filling to enter downward into the housing, thereupon to reeve through the same on being drawn from the package 3, and thereafter retain therein,

. through the coil.

thus: The top wall,-which is a bent-off extension of the near side wall 8 in Fig. 1 and overhangs the space of the housing, is formed with two tongues 9 and 10, both extending short of the other side wall so as .to expose from above a partof the bottom wallandother elements and to permit the filling to'enter the housing as stated. Tongue Sis curved gradually downward into the space of the housing, its vextremity being returnedin the generaldirectionlof the near sidewall in;

Fig. 1. TonguelOis bent vertically down-- wardly at its extremity, thus forming a hook lO whose forward edge is rearwardlyinclined; theforward edge 10 oftongue lO is alined'with the rear side of slit 7, being spaced from the part 11 of the shuttle bodyopposit'e it so that said slit isthusin effect extended. inward. The rear wall 8 has a hole 12 there in to which enters sidewise thereof and from the top of the walla narrow passage 12, and

- tongue 9, it will be noted, crosses this passage viewing the device lon'gitudinally (Figs. 5

I and v6). If the filling, extending from the package 3 forward, be at a .point forward of The tension lever is a length of. wire 13" the .hole 12 held downwardly it will enter 1 andis formed as follows It has abearing coil 1 13*fromwhich at one end thereof the wireeX- :tends to form an, arm 13 and from which at the other end thereof extends the main arm of the lever, the same 3 being substantially.

straight. When positioned in the shuttle the coil 13 rests on the bottom wall 8? of the housing. and'near the far side wall 8 and the end wall 8 with-its axis vertical; l l'is aful-f cruming screw tapped into thebottom wall jects through a hole. 15in the housing and in this cavity an elastic 17 which connects said arm with an adjusting screw l8 driven Arm-13 of the lever prointothe shuttle body. 1 The main arm of the lever, when the'latter is in its normal posi-- tion, held by the elastic 17 extends toward the right hand end of the shuttle and bears against the far side wall 8 At its free end I i filling enters downwardly into the shuttle cavity 24: to enter the crotch 13 it cannot become caught between the lever and the far side wall of the cavity but will be shunted into the crotch because the main arm of the lever presents a substantially straight top surface to the stretched filling clear to the free end of such arm.

The housing8 is secured in the shuttle body by one or more screws 1.9 which are exposed at the top and therefore freely accessible, so that the device can readily be removed for repairs. I

While, further, the filling has ready access downward to the tension lever when the threading operation is performed, the tension lever is easily removed for adjustment or replacement and its fulcruming screw 14 is also readily accessible without disturbing the housing in either case. 7 The filling is entered into the control of the 7 tension device by stretching it across the top of the shuttle to the right thereof and then causing a movement, one relatively to and past the other, with respect to the shuttle and the point to which the filling is held, so that a bight is formed in the filling which then en- I ters via the slit into the outlet 6, the result being that the filling is received in the crotch 13 of the tension lever and enters the hole 12 inthe rear wall of the housing and also becomes caught under the tongue 10, to thereupon be retained by its hook 10 This would be the operation if, on automatic replenishing of the filling in the shuttle when in the right hand box of the loom, the shuttle performed its first traverse to the left with the filling se-v remainder thereof upwardly exposed, and a top slit communicating with the outlet between the tongue and said end of the shuttle, in combination with a tension lever movable within the cavity toward said wall under the tongue and from the opposite wall and normally held toward the latter and having an upwardly open filling-receiving crotch norand a portion upstanding therefrom and provided with a filllng-catchlng tongue overhanging a part of said wall and leaving the remainder thereof upwardly exposed, the shuttle havinga lateral filling outlet and a top slit communicating therewith between the tongue and said end ofthe body, a tension device for the filling movable within the housing and adapted to be engaged by the filling when the same is caught the tongue, and a screw securing the housing in the body and driven through said exposed part of said wall from above anddownwardly into the y- 4 3. A shuttle having an upwardly open cave ity to receive a filling package, a fillingoutlet extending from the cavity through one side wall of the shuttle'and between the received package and one end of the shuttle and means to admit the filling into and thereupon confine the filling in said outlet, in combination with a tension lever arranged within said cavity and movable toward and from said wall and normally held toward the oppo site wall of the shuttle, and a fulcrum device on which said lever is fulcrumed and from which it projects toward said end of the shuttle, said lever being substantially straight from its fulcrum to its free end and having at said free end a depending portion forming an upwardly open crotch. adapted to receivethe filling cavity. g In testimony whereof we affix our signatures.
